The particularly rich and well‐documented examples of V‐22 and AW609 twin‐engined tiltrotors can be used to illustrate various architectural and conceptual options in terms of actuation for critical functions such as flight controls. Although these aircraft use hydraulically powered actuators, the example of their pylon conversion actuators illustrates well the specificities related to the transformation of high‐speed rotational motion into low‐speed translational motion, which can also be found on linear electromechanical actuators (EMAs). This chapter summarizes various solutions implemented on the pylon conversion actuators of the V‐22 and AW609 tiltrotors. The synchronization of pylon tilting is therefore exclusively obtained electronically, at the level of closed‐loop position control of pylon conversion actuators. The pylon conversion actuators are by far the richest in terms of redundant power architectures whose concepts are also applicable to the linear EMAs.
